TO ALL WHO IT MAY CONCERN:

Be it known that I, ALEXANDER VAIL, of Henry, in the county of Marshall, dnd State of Illinois, have invented a new and useful Improvement in Plows; and I do hereby declare the fllowing to be a full, clear, and exact description of the same, suicient to enable others skilled in the art to `rhich my invention apper tains to fully understand and use the same, reference being had to thc accompanying drawings, making part of this specification, in which#- Figure, 1 is u. top or plan'view of a plow illustrating my invention.

Figure 2 is u side elevation, illustrative of the operation.`

Figures 3, 4, and 5 are detail views hereinafter to be rcfcrred to.

Similar letters of reference indicate corresponding parts. iu the two figures.

My invention relates to a two-horse riding-plow, and is more particularly'desfigncd as an old-ground" plow, it being made controllable by means hereinafter fully specilied.

In the drawings- A represents, an axle-tre`e, which is supported-upon two wheels, B B', andtolsaid axle-tree is fastened a beam, C, which may be made laterally adjustable by wedges or otherwise, to enablje the plow to take more or 4less land. To this beam C the shank of the plow, D, is rigidly fastened, so that glie plow partakes of ull the movements of the bearn.

LAgkdrivers seat, S, is so mounted as to be somewhat behfndthe axletree A, thereby A.' Two houndsfEl-E", mwfbinged to the .freni-ignota? tlr s-rile tree, `and form at` their other ends a point of' attachment for the tongue, F, to which the double-tree G is fastened. Iheso hounds support two upright arms H H', joined together at top, andvserving as u. fulcum for a lever, I, whose forward end is connected by a rod or chain to the forward end ofthe beam C, while the other end is operated by the driver.

A slide, is fitted to work upon the top of the .beam C, which slide, when the forward end of the beam C is lowered,- (by means of the lever I,).is pushed forward, to ninintain the relative positions of the beam'nnd tongue, without the necessity of sustaining the lever I by hand.; The beam C may have a. guidewhee1 fastened to its front end, which p'rccedes the plow, and scciires a uniform depth of the furrow.

The wheel B', that runs in thefurrow, is about one foot larger in diameter than that on the land-side, which keeps tho plow in a. level position. Y

When the plow runs too deep, ,or meets an'obstruction, thedrivcr, by pulling back the slide K, can lift it immediately out ofthe ground by his own weight, the seat being so situated as to apply the necessary leverage.

The lever I is also used for keeping the plow raised as'long as the plowing is'to be suspended.

The vertical guide-ro`d I', rising from thevrear end'of the b eam C, is embraced by adoop, e, on the' lever I, and it may be provided witha series of apertures, to enable the lever to be retained `in any desired position, by a spring-detcnt. i i i In order to maintain the horizontal position of the axle, Ste., when the machine is travelling over a level road, as well as when one wheel isin the furrow and the other upon the land, I provide the smaller wheel B with adjustable journal b,p(s`e'e tig. 3,) formedv with or upon a socket-piece, b', which receives a stud, a, projecting from the end of the axle. A pin, a', serves to key the soclivet-piece b' to tho stud a, and thus retain the journal b in either the elevated or depressed position shown in iig. 3, (by red lines andV blue tint, respect- 'ively,) according as the machine is at work or passing over level ground.

" Having thus described my invention,what I-claim as new herein, and desire to secure by Letters Patent, is-

1. The beam C, supporting the plow D, and rigidly secured to the axle A, in combination with thc drivers seat S, the hinged hounds E E', and. tongue F, substantially as and for tho purpose herein set forth.

2. The slide K, arranged to operate in connection with the beam, hounds, and tongue, substantially as and for thc purpose described. i

3. The hinged hounds E E', in combination with a plow suspended from a beam, rigidly secured to the axle, substantially as described. f

A. The combination of the beam C, plow D, hinged hounds E E', tongue F, lever I, axle A, and drivers seat S, substantially as and for the purpose described` i f i ALEXANDER VAIL.
